Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.


This class uses a linear search algorithm to find entries in the list of delegates. A linear search algorithm is inefficient when working with a large number of entries. Therefore, when you have a large list, finding entries is slow.


For an example on using an EventHandlerList, see the sample in the "Optimizing Event Implementation" section in Defining an Event.
